Big Time Gaming · 2019Overview
Who Wants to Be a Millionaire Megaways transplants Big Time Gaming's Megaways engine into the iconic quiz-show format. Six reels, up to 117,649 ways to win, and every cascade triggers fresh symbol drops — the hallmark tumble that builds momentum.
How it plays
Bet from £0.20 to £20. Each spin generates a random number of symbols per reel (2–7), meaning paylines fluctuate wildly — sometimes 16,000 ways, sometimes over 100,000. Land winning combos and the symbols vanish; new ones fall to fill the gaps. Each tumble carries a multiplier that stacks, so a four-tumble run can multiply your win by 4×, 5×, or more.
The bonus round
Trigger free spins by landing three or more scatters. During the round, a locked multiplier metre climbs with every tumble — you're chasing higher and higher multipliers across your free spins. The bonus round is where the 50,000x payouts happen: long tumble chains, multipliers stacking, and the TV drama of holding your breath waiting for the next symbol to drop.
Who it's for
High-volatility hunters who love the game-show theme and can sit through long droughts waiting for one tumble sequence that ties together three free-spin multiplier boosts and pays the quarter.
Avoid if
You want steady, frequent small wins or prefer games that resolve quickly — Millionaire Megaways chases drama over consistency and can sit silent for 50+ spins.

Megaways generates 2–7 symbols per reel at random. Six reels × variable symbols = paylines that swing from 16,000 to 117,649. More symbols = more ways to match.
Free spins combined with tumble multipliers. Each cascade boosts the multiplier; chain four or five tumbles together and your base win gets multiplied 4× or 5×. That's where 50,000x hits happen.
